add-product · MCP Server MCP: Risk & Policy

WHAT IT DOES

What add-product does on MCP Server

AI agents use add-product to create or update resources in MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Server environment.

WHY IT NEEDS A POLICY

Why add-product needs a policy

This tool creates new records in a product catalog, which is a reversible write operation. It does not execute arbitrary code, delete data, or involve financial transactions. Severity is medium because catalog corruption or spam product injection could degrade service quality or require administrative cleanup, but the impact is limited to product data and reversible.

From the tool's definition Tool name 'add-product' and description 'Add a new product to the catalog' indicate creation of new data in a product database.
